MIKROE Matrix R Click

Matrix R Click is a mikroBUS™ add-on board with two red 5x7 matrices driven by two MAX7219 8-bit LED Display Drivers. The active area of each matrix is 7.62mm high and 5.08 mm wide. 7x5 is a standard resolution for displaying ASCII characters so the Click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. The Click communicates with the target MCU through the mikroBUS:tm: SPI interface with two separate Chip Select lines for each matrix (CSL for the left CSR for the right). This board is designed to use a 5V power supply.
